COKE-QUENCHING CAR.

Application filed January This invention relates to cars arranged to discharge their contents by gravity upon the opening of a door. While not limitedthereto the invention is particularly directed to the provision of a car forhandling coke and adapted to permit the same to, be drenched with water.

The coke quenching cars in use at coke oven plants receive incandescent coke from the carbonizing' chambers of the several ovens contained in a battery of ovens. The incandescent coke thus loaded on the quenching car is then propelled by an electric locomotive into a quenching chamber containing overhead pipes which spray water over the coke in the quencher car thus .thoroughly cooling it. The quenching car is then propelled by the locomotive and is brought in front; of a coke wharf into which the quenched coke is unloaded, thence delivered onto a belt conveyor, screened and loaded into railroad cars for shipment.

The floors-of thequenching cars heretofore used for receiving the incandescent coke to be quenched are usually constructed of supporting beams placed at intervals to which are secured cast iron plate sections. This construction does not provide a water tight bottom and as a consequence the door operating machinery under the car floor is subjectto the injurious effects of the hot impure water dripping on the working parts of the mechanism. It also has the added disadvantage of requiring very frequent replacement of .floor castings on account of i wear due to abrasion and cracking of plates due to sudden changes of. temperature, during the process of quenching coke. Constant attention and repairs due to wear and. tear on." air operated door. opening device,

damages to machinery due to leaky floors and the necessity of frequent-replacement of cast floor plates, areexpenses incurred by cars heretoforeused;which'increase the cost of coke produced. 7 My'invention aims to overcomethese objectionable features and also'to'minimize the initial cost of installation and the cost of maintenance." l p I' provide electrically operated means for "actuating the 'doors controlling the discharge of coke and form the floor in such a way and .of such materials that it performs the double function of preventing the rapid wearing awayof the car bottom "and also 28, 1925. Serial No. 5,318.

serves as a shield which prevents the drippage of water onto the door operating mechanism located beneath the floor.

An embodiment of the invention is ill lustrated in the accompanying drawings in which i Fig. 1 is a plan of a coke quenching car; Fig. 2 is a side elevation thereof;

Fig. 3 is an enlarged plan of the door op- I crating mechanism;

Fig. 4 is a side elevation in Fig. 3;

Fig. 5 is an enlarged cross-section on line 5-5 of Fig. 4;

' 6 is a diagram illustrating. a signal for indicating the open and closed partitions of the discharge door.

Referring in detail to the drawings; 10 and 12 represent standard railway car trucks of any suitable type which support the car frame 14 which includes suitable of parts shown longitudinal side walls 16 and 17 and crossbeams 18 at spaced intervals, Secured to the side walls 17 at spaced intervals are a series of uprights one of which is indicated at 20 .in Fig. 5. These serve'as columns or struts for supporting the upper longitudinal girder22 which forms a support for the upper ends of a plurality of inclined floor beams 24 the lower ends of which rest on an angle shaped member 26 secured to the side wall '16. A series of U shaped castings 28 are secured to the floor beams 24 at their lower ends and at their upper ends to longitudinal angle bars 30 at the top of the car. The castings 28 and bars 30 form supports for a grating 32, the lower end of which-is secured to the longitudinally extending angle bars 34:. These bars support a number of hinge brackets 36 which pivotally support the door 38 controlling the discharge of coke from the car. The door 38 is preferably made of a series of sections which,

however, are tied to one another by longi- V worm meshes with a worm wheel carried by the shaft 62 which is provided'on itsends with couplings 64 and 66. The latter are connected respectively to the shaftsections 68 and70 extending. longitudinally froln each side of the center of the car. These shafts: carry on their outer endscranks 72 and, 74L which are. connected by means of suitable pitman rods 76to. pivot bearings:78 secured. near. the lower ends. of; the door 38. This arrangement provides a simple. yet powerful electrically operated door mecha nisrm. The use of the flexible joints between the..motor. and. the. shaft 54'; relieves the drivingmotor. somewhat fromthe strain in starting and also provides a construction iniwhichino extreme accuracy is required in assembling or installing the door operating mechanism; the. flexible joint being adapted to yield somewhat to compensate f0I.'Slightmisalignment of parts. There is also some littleflexibility. at the couplings. 64. and .66.

To shield the door operating'mechanism from! the injurious effects which. would; result from; the drippage otquenching, water through the%fioo.r,.l provide a floor ofnovel construction. comprising a sheet metal. plate 89,. over which I. lay a course of hardiburned bnick, .thetexture of. which .is. adapted. to endure the-abrasionof the coke asv it is dis.- charged from the ovensiand also to: resist the wear) occasionedby the coke. sliding. oven the floor whom the. caris being. emptied, This construction. in addition to. resisting. wear andshedding"; water. also provides a floor bottom; which. can. be. readilyrenewed at a smalliexpensec v I Torensure. against running, the car with t'hezdoors open and. also to indicate to. an operator at. aremote pointv the. position of the doors, I; preferably provide a. signal operated: in. synchronism: with the discharge doori In. the construction illustrated, the signal. consists; of; twoelectric lights which WlllaUSllB'llYt e of different. color, one red, for example, indicating that. thedoors are open. and the other. green. indicating. thatthe doorsare closed T-heselights indicated at .82Fa2nd 8& respectively, will be located in the engineeris-cabr of the locomotive which. propelsi the coke. cars and connected by suitable wiring as: indicated. diagrammatically in Rig: 6:. Whenthe: door is open, the contact sector; 86 .on the drum 88 will-close the circuit through a: source-Of; energy indicated. at '90 through .the redrlight' 82,. and when the doors openzthe circuit through the green light. 8:4= will be broken. as. indicated and when the doors are.- closed this circuitv will also; he; closedi through the sector 92. on the drum 943. Tihewdrums 8&andz94-are carried by the section 70 of the door operating shaft and, therefore, they are. actuated. each time the doors-are. moved.

Though I have described with great particularity the specific construction of the embodimentof the invcntion illustrated, it is not to be construed that I am limited thereto as various modifications and substitutions of. equivalents may be made by those skilled in the art without departing from theinvention as. defined in the appended claims.
